[PATCH V2 00/10] media: hantro: imx8mq/imx8mm: Let VPU decoders get controlled by vpu-blk-ctrl

[Adam Ford]

Both the i.MX8MQ and i.MX8MM have G1 and G2 decoders.
The two decoders are similar, but the imx8mm lacks the
post-processor, so they will have distinct compatible flags.

From what I can tell, the G2 decoder wasn't working, so splitting
the i.MX8MQ VPU into G1 and G2 makes it easier to control them 
independently since the TRM of both the i.MX8MQ and
i.MX8MM list them as distinct IP blocks. This also allowed G2 to
become available.

With them being split, the power-domain can shift to the
vpu-blk-ctrl which is available on both i.MX8MQ and i.MX8MM,
but some of bits are different, so they'll have separate bindings.

Lastly, with the G1 and G2 operational, enable the i.MX8MM.
On the i.MX8MM, the clock speed of 600MHz was chosen to match
the default of the kernel repo from NXP and can be overwritten
by board files for anyone who under/over volts the power rail.

There seems to be some disagreement between the TRM and the Datasheet
for the imx8mq as to whether the speed should be 300MHz (TRM) or
600MHz (datasheet), so feedback from NXP would be very much
appreciated.

The repo used as the starting point was:
git://linuxtv.org/hverkuil/media_tree.git for-v5.17e

Fluster was run on both i.MX8MM and i.MX8MQ

At 600 MHz, the i.MX8MM had the following:

./fluster.py run -d GStreamer-VP8-V4L2SL-Gst1.0
Ran 55/61 tests successfully               in 8.299 secs

./fluster.py run -dGStreamer-H.264-V4L2SL-Gst1.0
Ran 90/135 tests successfully               in 71.200 secs

./fluster.py run -d GStreamer-VP9-V4L2SL-Gst1.0
Ran 139/303 tests successfully               in 218.079 secs

The i.MX8MQ had the following:

./fluster.py run -d GStreamer-VP8-V4L2SL-Gst1.0
Ran 55/61 tests successfully               in 7.732 secs

[PATCH V2 05/10] media: hantro: Allow i.MX8MQ G1 and G2 to run independently

[Adam Ford]

The VPU in the i.MX8MQ is really the combination of Hantro G1 and
Hantro G2. With the updated vpu-blk-ctrl, the power domains system
can enable and disable them separately as well as pull them out of
reset. This simplifies the code and lets them run independently
while still retaining backwards compatibility with older device
trees for those using G1.

[PATCH V2 06/10] arm64: dts: imx8mq: Enable both G1 and G2 VPU's with vpu-blk-ctrl

[Adam Ford]

With the Hantro G1 and G2 now setup to run independently, update
the device tree to allow both to operate.  This requires the
vpu-blk-ctrl node to be configured.  Since vpu-blk-ctrl needs
certain clock enabled to handle the gating of the G1 and G2
fuses, the clock-parents and clock-rates for the various VPU's
to be moved into the pgc_vpu because they cannot get re-parented
once enabled, and the pgc_vpu is the highest in the chain.

The vpumix power domain has a reset assigned to it, however
when used, it causes a system hang.  Testing has shown that
it does not appear to be needed anywhere.

[PATCH V2 08/10] dt-bindings: media: nxp, imx8mq-vpu: Add support for G1 and G2 on imx8mm

[Adam Ford]

The i.MX8M mini appears to have a similar G1 and G2 decoder but the
post-procesing isn't present, so different compatible flags are requred.
Since all the other parameters are the same with imx8mq, just add
the new compatible flags to nxp,imx8mq-vpu.yaml.

I believe the g1 and g2 _reg_names are now unused?

Re: [PATCH V2 00/10] media: hantro: imx8mq/imx8mm: Let VPU decoders get controlled by vpu-blk-ctrl

Hi Adam,

The series looks really great.

I believe you should be able to rebase on top of
media_tree master. As far as I can see, it contains the VP9
support you need.

Also, please cherry-pick the following fix from Benjamin

https://patchwork.linuxtv.org/project/linux-media/patch/20211208164418.848790-1-benjamin.gaignard@collabora.com/

This is queued and should land on the master branch very soon.

I imagine the reason H264 and VP9 tests take so long
is some pixelformat conversion somewhere. It would be great
if Fluster could have test vectors ready in the pixelformat
the hardware produces :-)

... in any case, the fact that fluster is passing is already
telling us the driver is in good shape. How many jobs is the above
running in parallel?

If you want to do some other tests, you can build a gstreamer
pipeline, with sync=false, and decode a few 1080p video, e.g.
https://jell.yfish.us/.

Something like gst-launch-1.0 filesrc ! decodebin ! fakevideosink, or
so.

Then, you can run the pipeline in parallel as many times as you want:

gst-launch-1.0 filesrc ! decodebin ! fakevideosink filesrc ! decodebin ! fakevideosink filesrc ! decodebin ! fakevideosink ...

(GStreamer lets you concatenate src ! sink src ! sink, in the same
gst-launch-1.0 invocation).

Looks great.

Any change you could give your acked-by or reviewed-by to the patches?
 Even if they need some work, I can carry those along to the next
revision when I do the work you request.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1569050

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

I have tested this series on top of media_stage/master branch
with IMX6MQ:

./fluster.py run -d GStreamer-VP8-V4L2SL-Gst1.0
Ran 57/61 tests successfully               in 32.725 secs

./fluster.py run -d GStreamer-H.264-V4L2SL-Gst1.0
Ran 89/135 tests successfully               in 131.632 secs

./fluster.py run -d GStreamer-VP9-V4L2SL-Gst1.0
Ran 146/303 tests successfully               in 304.345 secs

./fluster.py run -d GStreamer-H.265-V4L2SL-Gst1.0 -j 1
Ran 77/147 tests successfully               in 1047.211 secs

For this series:

You could expand this a bit more with Lucas' explanation and being 
explicit on the compatibility implications.

Otherwise, with that and indentation fixed:

Just 'i.MX8' so we don't have to change this everytime?

No point in more examples just for a different compatible.

Are you OK with i.MX8M?  8MQ, 8MM, and 8MP all appear to have G1 and
G2 decoders.  The i.MX8 is different.

No, the structures associated with these compatible flags telling the
driver what features are available have options for the post-processor
in the 8MQ which are not present in the 8MM.

Just as G1 and G2 are different blocks, their "post-processor"
features are really different too.

The G2 core typically produces a tiled format, NV12_4L4,
and it an inline post-processor to convert that to linear NV12.

How does this work on the 8MM? What pixel format does it
produce natively?

It's hard to imagine the G2 block doesn't do linear NV12,
so I'm inclined to think it has that post-processing feature.

Thanks,
